So we have a group of chicks, about 8 weeks old now, and 4 of them are cockerels. They have been picking on each other and inflicted small injuries to each other's beaks by their nostrils, which have been fine and heal quickly, but a hen got in the chick pen the other day and completely destroyed the upper beak of one of the cockerels. Right now He's drinking water, and I have him inside, and separatist. I'm guessing I should keep him separate, but I was wondering if his beak will ever grow back. Also he can eat, but it's difficult, and he can only eat things if they're in like a pile and he can get what's left of his upper beak in there.
